--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note while the patch fixes the reported issue it still ICEs the same way
when compiling with -g0 and linking with -g (as I would have expected).
That would be fixed by sth like the following but that then hides
issues with consistent -g as we ran into. It might be instead interesting
to make it more consistently fail by asserting early_dwarf here ...
(but I expect that to blow up in our face)
So I'm not going to fix this right now but will open a new bug for it.
